Bindings to the Metal framework

See Apple's docs and the general docs on framework crates for more information.

Metal has tools for validating that you're using it correctly, using these is highly recommended! See Apple's documentation on it, or run man MetalValidation to get information on environment variables.

Note: To use MTLCreateSystemDefaultDevice you need to link to CoreGraphics, this can be done by using objc2-app-kit, or by doing:

#[link(name = "CoreGraphics", kind = "framework")]
extern "C" {}

Example

Drawing a rotating triangle.
